Exynos5420 is an octacore SoC. This patch series enables the remaining 4 cores.

Changes in v2:
	- Changed the cpu node @unit-address value to reg property value.

Exynos5420 is octacore SoC from Samsung. Hence extend exynos-mct clocksource
driver to support 8 local interrupts.

Also extend dt entries for 8 interrupts.

Exynos5420 is octacore SoC from samsung.
Hence populate all the cpu node enteries.

you are NOT suppose to use '0x' in dt node name.
it should be  cpu4: cpu at 100 {
